El galileo positioning system it will be a global method of satellite travel perfected by the European Union with a civil usage, which is expected to be combined by some 30 commercialized satellites in three round planes, in a similar way and which will take about 14 hours to perfect a succession to the terrestrial orbit narrated.
History of the Galilean positioning system
At the end of the XNUMXth century, a group of nations of the European Union undertook to expose some rebound of insecurity change on GPS and GLONASS methods. Likewise, this group of countries distrusted that, in the event of a global armed jam, both the United States and Russia circumscribed or hindered the transition to these methods to the countries of the European Union, thus confining the military and civilian work in the area.
Faced with this, in the same way they exhibited some anxiety about the punctuality and safety of GPS schemes and GLONASS, fundamentally for the future.
In this context, the EU in conjunction with the European Space Agency, notified in 2003 the project designated GALILEO, an advanced geo-location system and duly processed by European entities, thus affirming the emancipation of the area and optimizing positioning business.
The established periods
For system execution Galilean positioning it was given:
Thesis (2000-2003)
Progress and ratification in orbit (2004–2008)
Dispersion (2008-2010)
Exploitation productive (as of 2010-2015)
The work of this system will be analogous to the present GPS and GLONASS for the purpose of achieving independence. At the same time, the European Space Agency feels that it is more accurate than the real ones, have a much more advanced set of techniques, underlining the high accuracy of the nuclear alarm clocks placed, which agree to accurately measure the time that the signal differs from the satellite to the receiver.
At the premiere of the plan, GALILEO was intended to be usable in 2008, but the credit difficulties that were provided and the inequalities between the collaborating countries have made the delay more than considerable.
Typologies methodologies and benefits
The Global System of Satellite Navigation, apart from facilitating independence in radio navigation and place-in-place, it will become a fully interoperable factor with GPS and GLONASS methods. In this order of ideas, by being able to provide two periodicities in its model interpretation, Galileo will offer place in the cosmos in real time with an accuracy of the order of 1 meter for the free procedure, and up to 1 cm in the disbursement procedure, something unprecedented in government regimes.
Likewise, the Galileo satellites, unlike those that create the GPS mesh, will exist in orbits slightly tilted toward the poles. Thus, their records will be more punctual in the areas adjacent to the poles, where the North American satellites markedly waste their punctuality.
In this way, it will guarantee the perpetual vacation of the service, except in excessive contexts, and, with the support of EGNOS, it will notify users in moments in the event of a satellite error. This makes it useful for utilities where safety is critical, such as employee rallies, car steering, or volatile traffic inspection. The use of EGNOS for civil aeronautics through the LPV medium is the one privileged by the International Civil Aviation Organization.
In the same way, the concerted use of Galileo and other GNSS systems will provide a large amount of taxes for all the corporations that benefit from the Cosmos.
Services provided by the Galileo positioning system
Galileo is envisioned for multimodal recipients. In order to recognize the unequal shortages, the system will supply some goods.
1. Open service
Aimed at applications for the general public. It will provide characters to facilitate time-determined research and will also have a free position. In this order of ideas, a really revealing fact is that positioning system Galileo will provide any person who is provided with a receiver to consent to this service, without the parvity of any kind of permission.
2. Service for applications in critical states
On the other hand, the second service provided by the Galileo positioning system is the one aimed solely at those applications that are in a critical state. In this sense, this service will be used exclusively for most cargo applications where human life could be in danger if the help of the radionavigation system products were dishonored without communication in real time.
3. Commercial Service
On the other hand, our third service belonging to the Galileo positioning system is undoubtedly the commercial one, this is basically focused on those applications of buyers that request a higher level of tributes than those provided by the accessible service. will offer complementary amount goods in exchange for a tax refund.
El commercial service adds two crossovers to open lane signs. This signal equivalent is favored through successful encryption, which will be processed by the service lenders and the subsequent GOC. The entrance will be inspected at the signal receiver level with address protection keys.
4. Regulated public service
In this case we are emphasizing a service system that many citizens consider to be a “robust” method and controlled income for all kinds of applications aimed at the exclusive environment of government entities. The PRS service will be used by beneficiaries such as customs and police centers.
It is important to note that all kinds of civil institutions will have the task of controlling approach to service Secret PRS whose input by country or beneficiary group will effect the adaptable security skills across Europe.
In the same way, you will have the duty to be active at all times and in any event, fundamentally when we are talking about any type of crisis that can be generated in different periods or when other products may be intercepted exclusively.
On the other hand, the positioning system Galileo is an emancipated service, in such a way that other goods can be rejected without this moving to the dismissal of said service. Likewise, one of the most important typologies that undoubtedly tends to stand out in this service is the strength of its signal, which protects it against the instruments of interruptions that are made with intention and attempts to intentionally manifest a varied signal. .
5. Search and rescue service
Another of the services offered by the Galileo positioning system is the one that helps with improvements to the existing Search and Rescue system. In this order of ideas, some of the usages that occur at this point are:
Reception
This is given in near real time of relief shipments transferred from anywhere on our planet.
Determined situation of alerts
Here we are speaking of terms that give in a few meters, specifically around about 5 km currently detailed.
Discovery by multiple satellites
In this case, this phase is used in order to avoid solitary confinement in situations dim from satellites.
Greater half of the sky fragment
When we are talking about a greater use of the cosmic fragment in the Galilean positioning system, we are mentioning the 30 satellites in earth orbit mean that they increase to four satellites in earth space which is in low focus and the three geo-stationary satellites of this system.
